Device for determining the resistance to cutting and damage of the running surface of vehicle tyres

摘要

A device for determining the resistance to cutting and damage of the running surface of vehicle tyres (5) has a hub (3) on which a vehicle tyre (5) can be fastened, individually in each case. The vehicle tyre (5) can roll on a section of roadway (17). The device is distinguished in that the hub (3) is arranged immovably during the testing, in that the section of roadway (17) can be moved essentially to and fro in the tyre rolling direction, and in that the vehicle tyre (5) and/or the section of roadway (17) can be driven. In an advantageous way, different speeds can be generated between tyre (5) and section of roadway (17), so that peripheral forces between tyre (5) and section of roadway (17) can be measured. <IMAGE>
